In June 2014, a small force of Islamic extremists routed the Iraqi army and seized control of Mosul, Iraq’s second-largest city. The militants then swept south, capturing Tikrit, until they occupied an area the size of the United Kingdom stretching across eastern Syria and northwestern Iraq. The militants, who had previously called themselves the Islamic State of Iraq and al-Sham, or ISIS, declared themselves the Islamic State and pledged allegiance to a mysterious figure named Abu Bakr al-
Baghdadi. Clad in a black turban and flowing black robes, Baghdadi addressed the world for the first time that July and announced the reestablishment of the caliphate, the kingdom of God on earth.

The speed of the Islamic State’s advance stunned onlookers and appeared to herald the collapse of the state system in the Levant after generations of autocracy, economic mismanagement, and political oppression. The Western powers, including those that had drawn the very borders the Islamic State was so gleefully dismantling, seemed paralyzed by the group’s sheer violence. With its mass executions documented in high-resolution video, its enslavement of women and children belonging to the non-Muslim Yazidi community, and its filmed beheadings of hostages, the Islamic State seemed intent on setting a brutal new standard for terrorist violence.

Yet just how new a phenomenon is the Islamic State? Terrorists have been waging violent insurgencies in various forms at least as far back as ancient Greece. Some have been motivated by political causes and have deployed indiscriminate violence in struggles for independence, in national resistance movements, or in pursuit of utopian secular ambitions. Others have been driven by religious fervor, inspired by apocalyptic visions, and led by charismatic prophets. The Islamic State’s rhetoric, filled with references to the end times and the fulfillment of messianic prophecies, may baffle most observers, but it is merely the latest expression of a long tradition of absolutist extremism. Within Islam, this tradition reaches back past al Qaeda and the twentieth-century theoreticians of jihad, through the rise of the ultraconservative movement of Wahhabism in the eighteenth century, and has its roots in ancient strains of Sunni theological thought.

For all the continuities between the Islamic State and past extremist movements, however, there are also stark differences in tactics and strategy. Whereas al Qaeda focused on spectacular attacks on the United States and showed some qualms about excessive violence toward fellow Muslims, for example, the militants who lead the Islamic State have focused on establishing a state in the Middle East and have shown no hesitation in massacring their coreligionists. And the Islamic State has distinguished itself from all past extremist organizations in the sophistication and scale of its use of social media and other forms of technologically advanced propaganda.

If the group is to be contained and ultimately destroyed, it is crucial for policymakers to understand precisely what differentiates it from past extremist movements. Not surprisingly, the past several months have witnessed a flood of new books addressing that subject. Three in particular merit attention; taken together, they represent the most authoritative portrait available of a movement that continues to mutate. The books show how the Islamic State represents a new and more dangerous evolution in the development of violent extremism and demonstrate its deep roots in Islamic history. They stress its control of social media and its apocalyptic vision, which are unique among current terrorist groups.

Yet the authors also agree that the Islamic State does not represent an existential danger to the West; its malignant impact will be felt most of all in the Muslim world. It will threaten the West with the possibility of mass-casualty terrorism, but “lone wolf” attacks of limited scope are more likely. Its goals are impossible for the organization to achieve, and a broad coalition of countries is now opposed to its expansion. Military efforts should be focused on containing the Islamic State rather than pursuing a decisive military victory. And the West should exploit its control of social media platforms to counter the group’s propaganda and to blunt its ability to spread its apocalyptic narrative online.


All three books tell a similar story about the rise of the Islamic State. As the terrorism experts Jessica Stern and J. M. Berger put it in ISIS: The State of Terror, “The rise of ISIS is, to some extent, the unintended consequence of Western intervention in Iraq.” In 2004, Osama bin Laden reluctantly gave his blessing for the Jordanian jihadist Abu Musab al-
Zarqawi to establish a local branch of al Qaeda in Iraq. In the words of Stern and Berger, Zarqawi was a “thug-turned-terrorist who brought a particularly brutal and sectarian approach to his understanding of Jihad.” It was Zarqawi who popularized the genre of filmed beheadings. Zarqawi, unlike bin Laden, believed that all Shiite Muslims should be killed and had no compunction about murdering Muslim civilians, to bin Laden’s consternation. Zarqawi’s bloody rampages and his fixation on instigating a sectarian war between Sunnis and Shiites horrified bin Laden and his deputy, Ayman al-Zawahiri, who repeatedly but unsuccessfully urged Zarqawi to change course. After Zarqawi’s death in a 2006 U.S. air strike, his organization rebranded itself as the Islamic State of Iraq (ISI).

The U.S. troop surge in Iraq in 2007 and Iraq’s so-called Sunni Awakening, when the country’s Sunni Arab communities turned against al Qaeda and other extremist militants, succeeded in greatly weakening ISI. Yet with the increasingly violent sectarianism of Iraqi Prime Minister Nouri al-Maliki, a Shiite, and the withdrawal of U.S. troops, Sunni communities found themselves disenfranchised, and ISI successfully exploited these fears to recover its strength. The outbreak of civil war in Syria in 2011 allowed the group to expand across the border, and it changed its name again, this time, in 2013, to the Islamic State of Iraq and al-Sham. Then, in June 2014, the group returned to northwestern Iraq, seized Mosul, and declared the caliphate.

Although undeniably dramatic, the group’s declaration of a new caliphate under Baghdadi was not an unprecedented move, nor is its exploitation of apocalyptic prophecies. Throughout Islamic history, many figures have claimed the title of caliph, or ruler of all Muslims, with varying degrees of success. Some of them have waged violent campaigns to establish their legitimacy. Islamic history is also replete with false prophets, some of whom have declared themselves to be the Mahdi, the savior that some schools of Muslim theology predict will appear before the apocalypse.

In The ISIS Apocalypse, William McCants, a specialist in radical Islamist movements in the Middle East, provides the most comprehensive analysis so far of the central role that Sunni traditions of apocalyptic fervor play in the Islamic State’s tactics and strategy. The group’s constant invocations of the Day of Judgment and the end of time have deep roots in Muslim history. McCants describes the “striking parallels” between the rhetoric and iconography of the Islamic State and those of the Abbasid Revolution of 750, when rebels flying black flags overthrew the second caliphate and established a third. During that period of upheaval, he writes, “apocalypse, caliphate, and revolution were inseparable, just as they are for the Islamic State.”

The Islamic State also has more recent antecedents. As McCants writes, the group’s “theology and method of engaging with scripture is nearly identical to Wahhabism, the ultraconservative form of Islam found in Saudi Arabia.” McCants notes that when the Islamic State needed to distribute educational materials to schoolchildren in its stronghold in Raqqa, Syria, “it printed out copies of Saudi state textbooks found online. Unsurprisingly then, most of the Islamic State’s hudud penalties [the fixed punishments specified in Islamic Scripture for the most egregious crimes] are identical to penalties for the same crimes in Saudi Arabia.”

The similarities between the Islamic State’s theology and Wahhabism are perhaps unsurprising, given the Islamic State’s roots in Wahhabi-influenced al Qaeda. In his compelling and meticulously researched book The New Threat, Jason Burke analyzes the origins of global jihad and the unique role of al Qaeda in shaping its development. Burke, a veteran foreign correspondent for The Guardian, traces the intellectual progenitors of the modern ideas of jihad that inspired bin Laden and his followers. The key figures include Sayyid Qutb, the theoretician of the Muslim Brotherhood and an iconic figure in Islamist militancy, and Abdullah Azzam, a charismatic Palestinian ideologue and polemicist whose call for Muslims to engage in “defensive jihad” was instrumental in mobilizing support and fighters for the war against the Soviets in Afghanistan. Qutb was hanged by Egyptian authorities in 1966, and Azzam was killed by a car bomb in 1989, but their ideas outlived them.

Bin Laden used the teachings of Wahhabism and the legacies of Qutb and Azzam to construct “a global narrative: of the cosmic struggle between good and evil, belief and unbelief, the mujahideen and the Crusader-Zionist Alliance,” Burke writes. This Manichaean view of the world, divided sharply between the forces of good and the forces of evil, between Muslims and infidels, would be even more strongly emphasized by the Islamic State in the years following its split with al Qaeda. As McCants argues, “The U.S. invasion of Iraq and the stupendous violence that followed dramatically increased the Sunni public’s appetite for apocalyptic explanations of a world turned upside down.” The masked armies of the Islamic State—its soldiers brandishing swords, storming cities, and daring the West to fight a final cataclysmic battle—have hardly appeared from nowhere. They are just another extremist group, made up of violent men driven by the same absolutist and apocalyptic impulses that have motivated similar organizations in the past.


And yet despite the similarities between the Islamic State and previous theocratic revolutionaries, from the Abbasids to the Wahhabis, the rise of the Islamic State represents something new and modern. The technologies of globalization offer contemporary radical extremists opportunities to reach mass audiences their predecessors could never have imagined, and the Islamic State has exploited these technologies more successfully than any of its contemporaries in the Islamist world. Stern and Berger’s book provides the most compelling analysis yet of the group’s creative and sophisticated propaganda efforts and its unprecedented use of social media. The Islamic State has several thousand active online supporters who operate in disciplined regiments. After the group posts something to the Internet—say, a beheading video—and it is authenticated, a second-tier regiment takes to Twitter to “retweet the link with a hashtag, then retweet each other’s tweets and write new tweets.” At coordinated times, online hashtag campaigns generate hundreds of similar tweets to create a “Twitter storm.” Other members upload the material to multiple platforms so that it remains available even if Internet providers pull the content down. If 
“al Qaeda was publicity-shy . . . ISIS, in contrast, is a publicity whore.”

This mass online campaign has attracted supporters from all over the world; some estimates place the number of foreign fighters in Iraq and Syria at around 20,000. Their reasons for joining the jihad vary, from the promise of living in and defending the world’s only ostensibly true Islamic state, to the opportunity for camaraderie and a sense of purpose, to the simple thrill of murder and the officially sanctioned practice of sex slavery—which The New York Times dubbed “a theology of rape.” Not much is known about the volunteers who have since returned to their native countries, perhaps disillusioned and repentant, or possibly plotting terrorist attacks. The phenomenon of fighters volunteering abroad is not in itself a new one—in the Spanish Civil War, thousands of Americans and Europeans volunteered to fight for the Republicans against the Nationalists. And jihadist organizations have always attracted foreign militants. Yet the scale of the Islamic State’s online presence and the ease with which a European extremist can travel to Syria have contributed to far greater numbers of Western volunteers serving with the group than ever fought for al Qaeda.

The Islamic State has distinguished itself from all past extremist organizations in the sophistication and scale of its use of social media.

The Islamic State is also different from recent jihadist movements in the size of the territory it controls. Unlike al Qaeda, which was never particularly interested in governing or in seizing and controlling land, and which preferred to launch attacks on the U.S. homeland, the Islamic State has always wanted a state in the Middle East. As Burke writes, “Zarqawi’s strategy was simple: to seize and hold real ground—to endure and expand, as the Islamic State’s motto later put it.” And this territory now generates a level of wealth for the Islamic State that al Qaeda never possessed. Many experts believe that the group is more than capable of financing itself through taxes and extortion, through which it takes in more than $1 million per day, as well as oil revenues. The Islamic State may well be the richest terrorist group ever.


The Islamic State is not as terrifyingly new as so much of the media coverage has claimed, but as these books illustrate, it represents a more dangerous evolution in the jihadist movement—one that must be understood accurately if it is to be defeated. In the current debate among historians, journalists, policymakers, and scholars about the nature of the group, there are those who seek to deny that it is rooted in Islamic traditions and who claim that the self-declared caliphate has hijacked a religion of peace and distorted its humane message. Such views ignore the fact that none of the three major monotheistic religions can be considered wholly peaceful: in their sacred texts, Christianity, Islam, and Judaism all contain elements of brutality and violence. But religions cannot and should not 
be understood by their texts alone. The lived history of a community of believers defines a religion; a great deal depends on how the custodians of a faith choose to interpret, defend, exploit, or abuse its sacred texts. The crusaders who slaughtered their way to Jerusalem in 1099 were as Christian as the Christians of the Renaissance and of today. The Islamic State is as much a part of Islam as Baghdad, Cairo, Córdoba, and Damascus were during their golden ages as centers of learning 
and high culture.

It is crucial, for the Islamic world above all, to recognize that the Islamic State has deep roots in Islamic traditions. Containing it will require the support of Arab and Muslim allies, and it is only by placing the group in the proper historical and cultural context that it can be demystified in the Muslim world. Once Muslims in the Middle East free themselves from the delusion that the Islamic State is a wholly alien phenomenon and recognize that the group’s false Mahdis and caliphs are but the latest in a long and bloody genealogy, they might come to see the fight against the Islamic State for what it is: a struggle to determine which tradition within Islam will define the religion going forward.

The authors of these three books do not foresee the group’s demise in the near future. They counsel Western powers against overreacting to the threat, which would undermine civil liberties at home and deepen the rift between Western countries and Muslim-majority states. But the Islamic State will not simply collapse on its own. The fight against the group is as much a war against an idea as it is a battle against armed militants. It must be fought not only on the frontlines of Iraq and Syria but also on every platform, electronic or otherwise, that the extremists use to spread their vision.
